VOLCANIC OUTBURST PROBABLE.

San Francisco, Cal., July 1.—News from Susanville, in the Sierra Nevadas, says that slight earthquake shocks continue and that the people have been so accustomed to the constant trembling of the earth that they pay no attention to it. The shocks, however, have revived recollections of old settlers who predict volcanic disturbances in the extinct craters, such as there were in 1850.

Susanville lies in a highly mountainous walled valley directly east of Lassen Butte, an extinct volcano 10,000 feet high. From its summit no less than forty extinct craters can be seen. Cinder Cone, which rises 600 feet above the level of the plateau, was in eruption in 1850. Two prospectors examined it and found Lake Saltafara, miles south of Cinder Cone, a center of volcanic forces. The lake was a mass of boiling water and mud and from it vast columns of flames shot up at intervals. The timber in the vicinity was on fire. Within the last few years there has seemed renewed activity in the internal fires and the present shocks point to the possibility of another great volcanic outburst which will find vent through some of the old craters.
